Why is This Exam Done?
Renal biopsies are typically performed to diagnose kidney cancer or other diseases. In some cases it is used to check on the success of kidney disease treatments or kidney transplants.
What Will Happen During the Exam?
You will be given a local anesthetic to numb the neck area, and a drug will be administered intravenously to provide you with the most comfort possible. Our experienced and caring physician will wait until the area is completely numb before proceeding. Once the area is numb the physician will make a small incision and using ultrasound guidance will place the needle into the liver tissue. It may be necessary to take more than once tissue sample. Once the sample is drawn it will be sent to a laboratory.
How Should I Prepare?
- You will be asked to change into a gown prior to the procedure
- Inform your physician of any medications you are currently taking
- After the procedure you may be monitored by a nursing staff for a few hours
- You will need to plan on having a friend or family member drive you home
